Use Faye pubsub with React Native

ReactNativeFaye.js

// make sure you npm install 'url' (the browserify port of the node api url module)
var url = require('url')
var Faye = require('faye/browser/faye-browser')

var API_URL = 'http://localhost:8000/faye'

// initialise fake window.location - same origin as api host
// required to use some faye transports which expect to deal with same-origin policy.
// url.parse return value looks kind of like window.location, if you squint just right
window.location = url.parse(API_URL)

var client = new Faye.Client(API_URL)
client.publish('/blah', {}) // works

Almost a year old, but what's the benefit of doing it like this? and what about using const Faye = require('faye') and not the browser?
